Uncomment immutable if you want immutable and remove 'shared' if you 
want multiple of this per thread (probably not).

/* immutable */ string[string] ctodtypes;

shared static this() {
     ctodtypes =
     [
         "void"      : "void",
         "uint32_t"  : "uint",
         "uint64_t"  : "ulong",
         "int32_t"   : "int",
         "int64_t"   : "long",
         "char"      : "char",
         "uint8_t"   : "ubyte",
         "size_t"    : "size_t",
         "float"     : "float"
      ];
}

void main() {
     ctodtypes["hello"] = "world";
}
